Title: Optical disk reproducing device
Inventor: SEKIGUCHI SATOSHI
IPC: G11B20/10
Filed: 1991-04-24
Abstract: PURPOSE:To attain the continuous reproduction by recording the regenerative signal at a high speed than the standard, reading out at the standard speed, cumulating the regenerator signal in the memory and interrupting the writing when the quantity is equal to the disk inversion time. CONSTITUTION:An optical disk 1 is read out at a high speed than the standard and the regenerative signal is written in the memory 7 with a clock WCK synchronized to it. The signal is cumulated in the memory 7 having a FIFO function since it is read out with a standard clock RCK from the memory. The cumulated signal quantity is detected with a detection circuit 11 and when the quantity is equal to the inversion time of the disk 1, the detection signal from the circuit 11 is sent to a pickup control circuit 10. The circuit 10 performs still or reverse jump at a proper time interval and the writing is interrupted during that period. Hence the memory capacity is made as much as the disk inversion time,so the over flow is prevented and the continuous reproduction is attained.
